Abstract

　カーディオトミー部（２）は、フィルタ（１０）と、フィルタの内側に配置された消泡材（２０）とを有する。フィルタの下端（１１ａ）は略一直線状又は曲線状にシール又は折り曲げられており、上方から見たとき、消泡材はフィルタの内周面に沿って環状に配置されている。心内血を導入する導管（９０）がカーディオトミー部内に上方から下方に向かって挿入されている。上下方向において、導管の下端が消泡材の下端と同一位置又はこれよりも下に位置しており、消泡材の下端面の水平方向面への投影図において、環状に配置された消泡材の長軸方向の外寸法をＲｕ１、短軸方向の外寸法をＲｕ２、消泡材の厚さをＴｕとしたとき、（Ｒｕ２－２×Ｔｕ）／（Ｒｕ１－２×Ｔｕ）≦０．２４を満足する。これにより、高い消泡特性を有するカーディオトミー部を備えた貯血槽を実現できる。
